Pricing

Here are details of the cloud service and on-premises installation subscriptions that we offer. All prices are in US$, and include tax based upon your location if applicable.

Free

The Free Plan (cloud service and on-premises installation) is aimed at individuals, and provides 1 workspace with all of the features needed to create software architecture diagrams and documentation. Specifically, it excludes team-based features such as role-based access, sharing links, workspace linking, full-text search, embedding diagrams from workspaces (e.g. iframe and Atlassian Confluence), and Slack integration.

Cloud service

Our cloud service allows you to get started with Structurizr quickly, without needing to host and update software on your own servers. You can read about how and where data is stored, and our privacy policy explains how we use your data. Please contact us for pricing above 25 workspaces.

On-premises installation

We also have a version of Structurizr that can be run on your own infrastructure (local servers or cloud), providing the majority of the same features found in the cloud service. A subscription grants you a perpetual license to use the software on your own infrastructure, although software updates will only be available for the duration of a valid subscription. See On-premises installation for more details.

Frequently asked questions

What is a workspace?

In Structurizr, a workspace is the wrapper for your software architecture model, views and supplementary documentation. Workspaces can be created using code, text, or the browser-based workspace editor. We recommend that a workspace contains the model, views and documentation for a single software system. See usage recommendations for more details.

Do subscriptions belong to users or workspaces?

A subscription belongs to a user account and, for the cloud service, the paid features are associated with the workspace(s) owned by the user who has the subscription. If you transfer a workspace from a paid subscriber to a free user, that workspace will lose the paid features. Subscriptions cannot be transferred between users.

Per team pricing, not per user?

Unlike typical software modelling and documentation tools, where the pricing is hundreds or thousands of dollars "per user", Structurizr's pricing is designed to be "per team", for whatever your own definition of a "team" is.

"Per user" licensing tends to result in a common anti-pattern where a small number of people end up being responsible for updating diagrams, with the resulting diagrams often being manually exported to static images for inclusion in documentation or wiki pages. We think that good software architecture diagrams and documentation should be accessible by everybody on the team, rather than just those lucky few individuals who are fortunate enough to have licenses for tooling.

Workspaces owned by a paid customer can be shared with free users, so you only need to purchase one subscription for your team.

Is there a trial of the paid features?

Yes, after signing up for our Free Plan, if desired, you can activate a free 14 day trial by using the link on your dashboard. This trial allows you to create up to 3 workspaces and unlocks all of the available features. This is obligation free and no payment details are required. After the trial period, your account will revert back to the Free Plan.

Do you manage credit card details yourself?

No, we use Braintree Payments (a PayPal company).

Which credit cards do you accept?

We accept Visa, Mastercard and American Express.

Refunds

All payments are strictly non-refundable. Please contact us for an extended trial if necessary before starting your subscription.

Cancelling a subscription

To cancel a subscription, and prevent it being renewed, use the link on your dashboard.

Changing a monthly subscription

There is currently no way to change an active subscription. If you'd like to move to a larger cloud plan, you will need to cancel your current subscription using the link on your dashboard to stop the recurring payment (this does not affect your existing workspaces), and re-subscribe when your current month expires. If you'd like immediate access to the larger plan, please raise a support ticket via your dashboard, after you've cancelled your current subscription. No data will be lost when a subscription is cancelled.

Updating credit card details

We do not have access to your credit card details, so it is not possible to change these to reflect a new credit card number or revised expiry date. To change your credit card details, please cancel your current subscription using the link on your dashboard, and follow the instructions in the confirmation e-mail about how to resubscribe to the same plan.

Failed payments

If a subscription payment fails for any reason, your subscription will be cancelled. In this situation, we will send you an e-mail with instructions about how to resubscribe to the same plan with alternative payment details.

EU tax for b2c transactions

Individuals in the EU are subject to tax at their local rate for the supply of digital services via the Internet (see Electronically supplied services for more details). EU registered businesses can enter their EU VAT number during the purchase process to have VAT deducted.

Purchase orders, invoicing and wire transfers

We're a small company, and due to the large overhead typically involved (supplier registration, vendor questionnaires, chasing late payment, etc) purchases for yearly subscriptions made via a purchase order/invoice and wire transfer will incur an additional $100 administration fee. Please contact help@structurizr.com with your business name, address and any purchase order details. Due to the EU VAT place of supply rules, EU registered businesses must also include their EU tax number to avoid being charged VAT at the local rate.

Resellers

Due to the additional overhead associated with indirect sales, a $100 administration fee will be added for all sales through resellers. No reseller discounts are available.

What happens to my workspaces when my paid plan expires?

Users on the Free Plan can create one workspaces so, when your paid plan expires, the workspace that you created first will be retained as-is. The other, more recent, workspaces will be retained too, but marked as read-only. You can still view the workspace content (via the UI and web API) but no changes can be made.

Do you support open source projects, academic establishments, and non-profit organisations?

Yes, free cloud-based plans are available for open source projects, academic establishments, and public speakers and trainers. Discounts are available for other non-profit organisations.
